The good news: Bobby survived her Undead school trip. Bad news: her best mate, Smitty, is missing. Bobby knows she's got to find him \. even if it means risking it all and going out into the starving-zombie-infested wastelands again. Even if it means taking fellow survivors \- including a couple of old frenemies \- along for the ride. And even if the zombies are not the only ones who are chasing them this time.
